Bolts in the brackets supporting the five roof mounted H2 tanks located at each end of each tank have the potential to loosen and drop out permitting movement of the bracket(s) and attached tank(s) with secondary movement in the associated system pipework. Under extreme braking conditions or if the vehicle is involved in a road traffic accident the roof tanks may become dislodged or become detached from the vehicle.

Fix: replacement of all bolts and nuts on the frame and frame attachment

On Wrightbus StreetLite (Micro Hybrid) vehicles that are fitted with electric cooling pack fans it is possible the electrical looms (cooling pack fan harness power cable and body harness looms) and the compressor delivery line hose may chafe on bodywork within the engine bay. This may affect the cooling fan operation and could lead to engine overheating or in extreme cases an outbreak of fire.

Fix: On affected vehicles check condition and routing of affected looms. Where necessary repair and re-route looms according to manufacturer's instructions.

The multi-circuit protection valve section of the Air Processing Unit (APU) has been incorrectly piped. The consequence is that the driver could release the park brake without sufficient pressure in the service brake circuits for them to function as the driver would expect. In this condition the red low pressure warning light for service brake circuits will either be independently illuminated or both together plus the low air pressure buzzer will be sounding.

Fix: Recall the vehicles that are likely to be affected to change the position of two air pipes on the APU unit.

It has been identified that the driver can inadvertently circumvent the correct operating procedure for the closing/opening of the rear plug and slide door. If the door operating sequence has been overridden then when the vehicle moves off from stationary the door can reopen a number of seconds after the vehicle has started to move off following the release of the park (halt) brake. Should this occur then the park (halt) brake will apply causing the vehicle to suddenly stop. The interlock will operate and the door will not reopen if the vehicle has exceeded 5 mph.

Fix: Recall all affected vehicles to upgrade the Kibes software.

Bolts (identified by CFL marking on head) connecting the lower wishbone assemblies to the vehicle chassis may be out of specification and at risk of failure. The failure of a single bolt is expected to have no adverse effect on the handling or integrity of the vehicle. A secondary failure mode on more than one bolt is likely to result in an unstable vehicle that will be difficult to control and will not handle in a normal way. The risk is that the driver could lose control of the vehicle.

Fix: Recall the vehicles that are likely to be affected and where a lower wishbone assembly is found to besecured with bolts marked �CFL� the bolts will be replaced with a bolt manufactured by a different supplier. All eight bolts in the lower wishbone assemblies irrespective of the manufacturer of the originally fitted bolt will be replaced when one or more bolts with the �CFL� marking are replaced.

Due to a software error in one of the vehicle's ECU's it is possible that if a passenger or occupant operates the front service door emergency controls (interior and exterior) when the vehicle is travelling in excess of 5km/hour then the front service door will function and open. This will only occur if the brake pedal is being pressed at the same time as the emergency control is operated. This could result in a passenger or occupant falling from the vehicle.

Fix: Recall all affected vehicles to update the software for the operation of the front service door.
